I remember getting a real 50Hz transformer with a Ventaxia fan in the

available for lights. They would, of course, form the basis for a nice

mode one with proper smoothing.

I suppose it depends what bits you have lying around. Small wall wart PS
are pretty cheap - but one which delivers several amps might be cheaper if
you have a free mains transformer for it.
